NAME
     Sun Grid Engine - a facility  for  executing  UNIX  jobs  on
     remote machines

DESCRIPTION
     Sun Grid Engine is a facility for executing UNIX batch  jobs
     (shell  scripts) on a pool of cooperating workstations. Jobs
     are queued and executed remotely on  workstations  at  times
     when  those  workstations  would  otherwise  be idle or only
     lightly loaded. The  work  load  is  distributed  among  the
     workstations in the cluster corresponding to the load situa-
     tion of each machine and the resource  requirements  of  the
     jobs.

     User level checkpointing programs are supported and a  tran-
     sparent    checkpointing    mechanism   is   provided   (see
     <B><A HREF="../htmlman1/sge_ckpt.html?pathrev=V62u5_TAG">sge_ckpt(1)</A></B>).  Checkpointing jobs migrate  from  workstation
     to  workstation without user intervention on load demand. In
     addition to batch jobs, interactive jobs and  parallel  jobs
     can also be submitted to Sun Grid Engine.

USER INTERFACE
     The Sun Grid Engine user interface consists of several  pro-
     grams which are described separately.

     <B><A HREF="../htmlman1/qacct.html?pathrev=V62u5_TAG">qacct(1)</A></B>
          <I>qacct</I> extracts arbitrary  accounting  information  from
          the cluster logfile.

     <B><A HREF="../htmlman1/qalter.html?pathrev=V62u5_TAG">qalter(1)</A></B>

     <B><A HREF="../htmlman1/qmake.html?pathrev=V62u5_TAG">qmake(1)</A></B>
          <I>qmake</I> is a  replacement  for  the  standard  Unix  <I>make</I>
          facility.  It extends make by its ability to distribute
          independent make steps across  a  cluster  of  suitable
          machines.

     <B><A HREF="../htmlman1/qmod.html?pathrev=V62u5_TAG">qmod(1)</A></B>
          <I>qmod</I> allows the owner(s) of  a  queue  to  suspend  and
          enable  all  queues  associated  with  his machine (all
          currently active processes in this queue are also  sig-
          naled)  or  to suspend and enable jobs executing in the
          owned queues.

     <B><A HREF="../htmlman1/qmon.html?pathrev=V62u5_TAG">qmon(1)</A></B>
          <I>qmon</I> provides a Motif command interface to all Sun Grid
          Engine functions. The status of all or a private selec-
          tion of the configured queues is displayed  on-line  by
          changing colors at corresponding queue icons.

     <B><A HREF="../htmlman1/qquota.html?pathrev=V62u5_TAG">qquota(1)</A></B>
          <I>qquota</I> provides a status listing of all currently  used
          resource quotas (see <B><A HREF="../htmlman1/sge_resource_quota.html?pathrev=V62u5_TAG">sge_resource_quota(1)</A></B>.)

     <B><A HREF="../htmlman1/qresub.html?pathrev=V62u5_TAG">qresub(1)</A></B>
          <I>qresub</I> creates new jobs by copying currently running or
          pending jobs.

     <B><A HREF="../htmlman1/qrls.html?pathrev=V62u5_TAG">qrls(1)</A></B>
          <I>qrls</I> releases holds from jobs  previously  assigned  to
          them e.g. via <B><A HREF="../htmlman1/qhold.html?pathrev=V62u5_TAG">qhold(1)</A></B> (see above).

     <B><A HREF="../htmlman1/qrdel.html?pathrev=V62u5_TAG">qrdel(1)</A></B>
          <I>qrdel</I> provides the means  to  cancel  advance  reserva-
          tions.

     <B><A HREF="../htmlman1/qrsh.html?pathrev=V62u5_TAG">qrsh(1)</A></B>
          <I>qrsh</I> can be used for various purposes such as providing
          remote  execution  of  interactive applications via Sun
          Grid Engine comparable to the  standard  Unix  facility
          rsh,  to  allow for the submission of batch jobs which,
          upon execution, support  terminal  I/O  (standard/error
          output  and  standard  input)  and terminal control, to
          provide a batch job  submission  client  which  remains
          active  until  the job has finished or to allow for the
          Sun Grid  Engine-controlled  remote  execution  of  the
          tasks of parallel jobs.

     <B><A HREF="../htmlman1/qrstat.html?pathrev=V62u5_TAG">qrstat(1)</A></B>
          <I>qrstat</I> provides a status listing of all advance  reser-
          vations in the cluster.

     <B><A HREF="../htmlman1/qrsub.html?pathrev=V62u5_TAG">qrsub(1)</A></B>

          reservation to Sun Grid Engine.

     <B><A HREF="../htmlman1/qselect.html?pathrev=V62u5_TAG">qselect(1)</A></B>
          <I>qselect</I> prints a list of queue names  corresponding  to
          specified  selection criteria. The output of <I>qselect</I> is
          usually fed into other  Sun  Grid  Engine  commands  to
          apply actions on a selected set of queues.

     <B><A HREF="../htmlman1/qsh.html?pathrev=V62u5_TAG">qsh(1)</A></B>
          <I>qsh</I> opens an interactive shell (in an  <B><A HREF="../htmlman1/xterm.html?pathrev=V62u5_TAG">xterm(1)</A></B>)  on  a
          low  loaded  host.  Any kind of interactive jobs can be
          run in this shell.

     <B><A HREF="../htmlman1/qstat.html?pathrev=V62u5_TAG">qstat(1)</A></B>
          <I>qstat</I> provides a status listing of all jobs and  queues
          associated with the cluster.

     <B><A HREF="../htmlman1/qtcsh.html?pathrev=V62u5_TAG">qtcsh(1)</A></B>
          <I>qtcsh</I> is a fully compatible replacement for the  widely
          known  and  used Unix C-Shell (<I>csh</I>) derivative <I>tcsh</I>. It
          provides a command-shell with the  extension  of  tran-
          sparently distributing execution of designated applica-
          tions to suitable and lightly loaded hosts via Sun Grid
          Engine.

     <B><A HREF="../htmlman1/qsub.html?pathrev=V62u5_TAG">qsub(1)</A></B>
          <I>qsub</I> is the user interface for submitting a job to  Sun
          Grid Engine.
